I just started running BIRT on an application server. The setup is classical: Apache Tomcat + BIRT 4.2 runtime. When I am trying to run the report that uses integrated security, I get the following error:
Nov 12, 2012 10:02:53 AM com.microsoft.sqlserver.jdbc.AuthenticationJNI <clinit>
WARNING: Failed to load the sqljdbc_auth.dll cause : no sqljdbc_auth in java.library.path

Where would I need to put sqljdbc_auth.dll file so that BIRT sees it?
I tried putting it into the ....\\Apache_Tomcat_7.0.32\webapps\birt-viewer\WEB-INF\lib folder but it does not seem to work.

Is this something that I have to do on a server side or should the .rptdesign file contain the link to the sqljdbc_auth.dll via some other configuration?
